To say Liam Payne died "because of drugs" is a little exaggerated. According to TODAY, Payne's toxicology report stated that the fall from the hotel led to severe injuries and health officials declared him dead on the scene. However, a plethora of drugs were found in his hotel room, along with a great amount in his system at the time of his death, including methamphetamine, MDMA, ketamine, pink cocaine, and crack. The New York Times reiterates this. To say that he died because of drugs implies he overdosed, which could be true (we don't know exactly at this time). However, his assumed ultimate cause of death according to many news sources and the toxicology report was his 3-story fall from his hotel, not exclusively the drugs in his system.
